Explanation:
A volcano on
Krakatoa
is still erupting.
Perhaps most famous for the powerfully explosive
eruption in 1883 that killed tens of thousands of people, ash from a
violent eruption might also have temporarily altered Earth's climate as long as 1500 years ago.
In 1927, eruptions caused smaller
Anak Krakatau to rise from the sea, and the
emerging volcanic island continues to grow at an average rate of 2 cm per day.
The latest
eruption of Anak Krakatau started in 2008 April and continues today.
In
this picture, Anak Krakatau is seen erupting from
Rakata, the main island of the Krakatoai group.
High above, stars including the Big Dipper are clearly apparent.
